Shutdown Mac Objective C

I need to be able to implement methods of:

  • Shutdown
  • Restart
  • Logoff
  • Sleep

On a Mac, I am using XCode but can't seem to figure out the code to perform these actions.

Can anyone help me out here?

Thanks

Solution

  • A trivial/lazy way do this is via some simple inline Applescript:

    NSString *scriptAction = @"restart"; // @"restart"/@"shut down"/@"sleep"/@"log out"
NSString *scriptSource = [NSString stringWithFormat:@"tell application \"Finder\" to %@", scriptAction];
NSAppleScript *appleScript = [[NSAppleScript alloc] initWithSource:scriptSource];
NSDictionary *errDict = nil;
if (![appleScript executeAndReturnError:&errDict]) {
    NSLog(@"%@", errDict); 
}
